STARTING OR STOPPING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 791,986, dated June 6, 1905.

Original application filed September 19,1899, Serial No. 780,979. Divided and this application filed August 3, 1900. Renewed May 8,

1905. Serial No. 259,431.

To all, whom, it may concern.-

Be it known that I, RONALD FnANoIs Mo- FEELY, acitizen of the United States of America, and a resident of Beverly, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Starting and Stopping Mechanism, of which the following, read in connection with the accompanying drawings, is a specification.

Of the accompanying drawings, Figure l is a side elevation, partly in section, of mechanism embodying this invention. Fig. 2 is an elevation of a central vertical longitudinal section showing parts of the mechanism connected with the machine-base. Fig. 3 is an elevation of a section showing parts of the mechanisim connected with the machine-head. Figs. 4 and 5 are duplicates of Fig. 3, showing the parts in difi'erent'positions. Fig. 6 is an elevation of a section on line 74 of Fig. 3. Fig. 7 is a plan of a section taken on line 75 of Fig. 3. Fig. 8 is an elevation of a section online 76 of Fig. 9. Fig. 9 is a plan of a section on line 77 of Fig. 3.

The mechanism represented comprises a pedestal A and head B. In the head B is journaled the shaft D, which, it will be understood, is the shaft operated by the starting and stopping mechanism. Obviously the shaft D may be suitably connected with different mechanisms which it is desirable to operate therefrom.

A shaft 960, journaled in the machine-base, carries a fixed pulley 962, to which the primary power is applied from any convenient source. Said pulley has a flange 964, the face whereof constitutes one member of a friction-clutch. The pulley 966 runs loose on the shaft 960 and has a flange 968, constituting the other member of said friction-clutch. In the hub of said pulley 966 is a groove 970, which receives the inturned end of a connecting-plate 979., extending from the collar 974, which collar is movable endwise of the shaft 960. A spring 978, secured at one end to a fixed part of the pedestal or frame and at the other end to the movable collar 974, operates normally to hold clutch member 968 out of engagement with the member 964. The part 976 has a wedgeface 980 in engagement with the collar 974. By an upward vertical movement of said part 976 the collar 974, and consequently the pulley 966, are moved to carry the flange 968 into engagement with flange 964, thus causing the machine to start. Connected with the part 976 is a rod 984, having its top end soclzeted in the head and resting on the spring X (See Fig. 3.) Said spring has its other end on the ledge X and when permitted so to do it operates to lift the rod, and consequently to start the machine. A reverse movement of said part 976 allows the spring 978 to act to separate the flanges, causing the machine to stop. The stopping is made more effective by abrake-shoe 982, which to that end is supported on rod 984 in position for bearing upon the wheel 986. Said wheel has connection with the shaft D and also has connection with the pulley 966 by a belt X. In the slide X is a fixed stud X whereon turns the roll X Springs X X, soeketed in the slide X have end bearing on the ledge X and actuate the slide X upwardly, thereby keeping the roll X in engagement with the working face of cam X on shaft D. Connected with the slide X is a plate X, the connection being made by a clamping-boltX,which,havingscrew-threaded engagement with slide X is movable to allow for adjusting the position of said plate X. The plate X* has its bottom end normally resting on the upwardly projecting limb m of the slide X, which, it will be observed, has a projecting lug X entering a suitable recess in the brake-shoe 982 for permitting movement of slide X horizontally against the resistance of spring X. The cam X on shaft D comprises two oppositely-disposed cam-rises, one of which, X is shown, whereby the roll X is forced to move downwardly. This movement, through the slide X plate X and slide X, in one position of the parts depresses the brake-shoe 982 into. bearing with the wheel 986 and also depresses the rod 984, compressing the spring X so that when permitted to do so it will lift the rod. The treadle X has connection with rod X, the top end whereof is socketed in the head B and has the wedge-face X in engagement with a similar face on the slide X Supported pivotally by a pin X on slide X is a lever X, having its rear end normally bearing against the slide X, as indicated at point X X, Fig. 3.

In starting the machine the workman depresses treadle X and thereby causes an upward movement of the rod X whereby slide X is pushed backwardly, carrying with it the lever X, and thereby forcing the slide X backwardly, carrying limb m from under the plate X whereupon the spring .4. is allowed to operate for lifting the rod 984, and consequently starting the machine, the parts taking the position shown in Fig. 5. Since the cam X is now rotating, the rise or projection X recedes from the roll X, whereupon the springs X X' lift the slide X, and consequently the plate X, carrying it upwardly sufficiently to permit the slide X" to move forwardly under the influence of the spring X whereby the limb m is again set directly under the plate X. (See Fig. 4.) The rear end of the lever X will now stand. under the slide X, and one of the rises of the cam X next depresses the roll X carrying with it the slide X, and consequently the plate X, which in turn depresses the slide X carrying with it the rod 984 against the tension of spring X and forcing the brake-shoe 982 into engagement with the Wheel 986. The wedge 980 is simultaneously moved to permit the spring 978 to act for retracting the flange 968, whereupon the machine will stop. It is supposed that all this time the workman has retained the lever X in the depressed position, so that the rear end of the lever X .has been depressed against the spring X and still remains under the slide X, as shown by dotted lines in Fig. 4. It may now be observed, first, that the machine has stopped even while the starting-lever X" has remained depressed, and, secondly, that in order to restart the machine lever X must be lifted to the normal position, and thereby reversely move the rod downwardly and allow the spring to act for returning the slide X and consequently the lever X, to their normal positions, whereupon the spring X will reversely lift the rear end of the lever X and set it in line against the slide X" preparatory for the next starting operation, which may then be effected by depressing the lever X, as before stated. By this mechanism the stopping of the machine at a predetermined point in the cycle of its general operation is made to take place independently of the starting-lever, and accidental restarting of the machine is avoided. The mechanism also comprises the block X, which, being mounted to permit turning on the rod 984, has its top end adapted to enter the recess X in head, B, and it also has a handle extension whereby it may be turned on rod 984 for bringing its said top end into and out of alinement with said recess X Obviously when in such alinement it will be lifted into said recess by an upward movement of rod 984, incidental to starting of the machine, as before described; but when not in such alinement it will strike against the head, thereby preventing the said upward movement of rod 984, and consequently preventing the starting of the machine. In the said handle extension is aspring-actuated plunger X adapted for entering notches X X in the brakeshoe 982, whereby to hold the block against accidental displacement. This block is intended for use particularlywhenever it may be desirable to leave the machine for a time unattended and also whenever it may be desirable to lock the machine against possible starting while the workman is making changes or adjustments in and about the machine.

Vhile the mechanism of this application obviously is not limited to use in connection with any particular machine, it is well adapted for employment with pulling-over or like machines. Letters Patent of the United States No. 663,777, granted to me December 11, 1900, show such amachine equipped with the starting and stopping mechanism described and claimed in the present application, and this application is a division of the original application which resulted in the grant of said patent.
